50 Ofi the Australian Haliotidce, 



very many years afterwards. It is stated to be found in 

 New Zealand only, whereas it is strictly an Australian 

 species, common at Port Phillip, and, as Dr. Milligan in- 

 forms me, in the islands of Bass's Straits : he has also found 

 it on the north coast of Tasmania. Among numerous ex- 

 amples in Dr. Milligan's cabinet there is not one specimen 

 at all coloured like this figure, which, from this and the 

 above circumstance regarding its locality, seems to throw a 

 doubt even on the identity of the species : the description, 

 moreover, is so short, and therefore imperfect, that it is 

 quite impossible to arrive at any conclusion on this point ; 

 certain it is, however, that not a single instance has yet 

 come to my knowledge of any species of Haliotis being 

 found both in Australia and New Zealand. In a natu- 

 ral arrangement this should be placed close to H. Califor- 

 niensis, and any other which have the open apertures of 

 the spiracles so numerous, and small and depressed. 

 Whether the species called glabra by the author, and figured 

 on PI. 1, fig. 2, should come in with the small-holed species 

 is uncertain ; never having seen the species (which I once 

 possessed in England, and is here very well figured), either 

 in Australia or New Zealand, I very much question the 

 correctness of its presumed habitat. 



We must here notice another species, stated to be also 

 an inhabitant of Australia, and called, without reference to 

 any authority, Haliotis rugoso-plicata, — Plate 3, fig. 7, — 

 a compound name, which, if the rules of nomenclature laid 

 down by the princes of science are to be adhered to, cannot 

 be admitted. True, it is a species apparently answering to 

 this that has been described by Lamarck under the name of 

 Australis, but as there appeared some discrepancy I could 

 not reconcile that description with a species in the Bligh 

 collection, and I accordingly considered it expedient to
